Dark green represents the lowest elevation and dark brown the highest Surrounded by the Indian and Pacific oceans,[N 6] Australia is separated from Asia by the Arafura and Timor seas, with the Coral Sea lying off the Queensland coast, and the Tasman Sea lying between Australia and New Zealand. The world's smallest continent and sixth largest country by total area, Australia—owing to its size and isolation—is often dubbed the "island continent" and is sometimes considered the world's largest island. Australia has 34,218 km (21,262 mi) of coastline (excluding all offshore islands), and claims an extensive Exclusive Economic Zone of 8,148,250 square kilometres (3,146,060 sq mi). This exclusive economic zone does not include the Australian Antarctic Territory Mainland Australia lies between latitudes 9° and 44° South, and longitudes 112° and 154° East. Australia's size gives it a wide variety of landscapes, with tropical rainforests in the north-east, mountain ranges in the south-east, south-west and east, and desert in the centre. The desert or semi-arid land commonly known as the outback makes up by far the largest portion of land. Australia is the driest inhabited continent; its annual rainfall averaged over continental area is less than 500 mm. The population density is 3.4 inhabitants per square kilometre, although a large proportion of the population lives along the temperate south-eastern coastline. Geography and environment Fitzroy Island, one of 600 islands within the main archipelago of the Great Barrier Reef The Great Barrier Reef, the world's largest coral reef,[141] lies a short distance off the north-east coast and extends for over 2,000 km (1,200 mi). Mount Augustus, claimed to be the world's largest monolith, Exclusive Economic Zone An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has special rights regarding the exploration and use of marine resources, including energy production from water and wind. It stretches from the ou Australia Is the world's largest island. Science and technology In 2019, Australia spent A$35.6 billion on research and development, allocating about 1.79% of GDP. A recent study by Accenture for the Tech Council shows that the Australian tech sector combined contributes $167 billion a year to the economy and employs 861,000 people. The country's most recognized and important sector of this type is mining, where Australia continues to have the highest penetration of technologies, especially drones, autonomous and remote-controlled vehicles and mine management software.[278] In addition, the Australian recent startup ecosystem is growing annually at rates of 5.8%, and the Sydney and Melbourne ecosystems are already valued at $25 billion. Australia consistently has ranked high in the Global Innovation Index (GII). In 2021, Australia ranked 25th out of the 132 economies featured in the GII 2021, down from being 22nd in 2019. With only 0.3% of the world's population, Australia contributed 4.1% of the world's published research in 2020, making it one of the top 10 research contributors in the world. CSIRO, Australia's national science agency, contributes 10% of all research in the country, while the rest is carried out by universities. Energy Main articles: Energy policy of Australia and Renewable energy in Australia In 2003, Australia's energy sources were coal (58.4%), hydropower (19.1%), natural gas (13.5%), liquid/gas fossil fuel-switching plants (5.4%), oil (2.9%), and other renewable resources like wind power, solar energy, and bioenergy (0.7%).[271] During the 21st century, Australia has been trending to generate more energy using renewable resources and less energy using fossil fuels. In 2020, Australia used coal for 62% of all energy (3.6% increase compared to 2013), wind power for 9.9% (9.5% increase), natural gas for 9.9% (3.6% decrease), solar power for 9.9% (9.8% increase), hydropower for 6.4% (12.7% decrease), bioenergy for 1.4% (1.2% increase), and other sources like oil and waste coal mine gas for 0.5%. In August 2009, Australia's government set a goal to achieve 20% of all energy in the country from renewable sources by 2020. They achieved this goal, as renewable resources accounted for 27.7% of Australia's energy in 2020
